Inscribed on the tomb of an Anglican Bishop in Westminster Abby
(circa 1100 A.D.):

When I was young and free and my imagination had no limits, I dreamed of changing the world. As I grew older and wiser, I discovered the world would not change, so I shortened my sights somewhat and decided to change only my country.But it, too, seemed immovable.As I grew into my twilight years, in one last desperate attempt, I settled for changing only my family, those closest to me, but alas, they would have none of it.And now, as I lie on my deathbed, I suddenly realize: If I had only changed myself first, then by example I would have changed my family.From their inspiration and encouragement, I would then have been able to better my country, and who knows, I may have even changed the world.

From Eckhart Tolle, "The Power of Now":

True change happens within, not without.

If you feel called upon to alleviate suffering in the world, that is a very noble thing to do, but remember not to focus exclusively on the outer; otherwise, you will encounter frustration and despair. Without a profound change in human consciousness, the world's suffering is a bottomless pit. So don't let your compassion become one-sided. Empathy with someone else's pain or lack and a desire to help need to be balanced with a deeper realization of the eternal nature of all life and the ultimate illusion of all pain. Then let your peace flow into whatever you do and you will be working on the levels of effect and cause simultaneously.

This also applies if you are supporting a movement designed to stop deeply unconscious humans from destroying themselves, each other, and the planet, or from continuing to inflict dreadful suffering on other sentient beings. Remember: Just as you cannot fight the darkness, so you cannot fight unconsciousness. If you try to do so, the polar opposites will become strengthened and more deeply entrenched. You will become identified with one of the polarities, you will create an "enemy," and so be drawn into unconsciousness yourself. Raise awareness by disseminating information, or at the most, practice passive resistance. But make sure that you carry no resistance within, no hatred, no negativity. "Love your enemies," said Jesus, which, of course, means "have no enemies."

Once you get involved in working on the level of effect, it is all too easy to lose yourself in it. Stay alert and very, very present. The causal level needs to remain your primary focus, the teaching of enlightenment your main purpose, and peace your most precious gift to the world.
